IMPROVEMENT IN ROLLING-MILL APPARATUS.

Specification forming part of Letters Patent No. 176.996, dated May 2,1876 application filed March 1, 1876,

To all whom it may concern:

Be it known that we, JOHN M. PRICE, of Syracuse, in Onondaga county, andWM. LEWIS, of the city and county of New York, both of the State of NewYork, have invented certain Improvements in Attachments toBolling-Mills, of which the following is a specification I Our inventionrelates to the manipulation of the hot iron or steel in the process ofrolling from the pile or ingot from the first pass to the last one, orfinishing-groove, and is applicable to various kinds of work, as sheet,angle, girder, rafter, and T iron of various patterns, and moreparticularly to railroadrails. 1

It is designed to greatly diminish the number of attendantsnecessary,'and to do their work automatically, so that two men and a boycan do the work heretofore requiring ten men, and, by the use ofindependent feed rollers above the receiving and delivering platforms,and actin gin conjunction with them when they arrive at the properposition for delivery, to deliver the pile or ingot to the rolls, and,when the billet comes from'jthe last pass of the first set of rolls, totransfer it quickly and accurately to the second set, to be fed andre-fed until finished.

- In the accompanying drawings, Figure 1 is an end view of an ordinarythree-high rail or girder mill, with attachments embodying ourinvention, as seen from m, Fig. 2. Fig. 2 is a plan of the same. Fig. 3is an end view from the opposite end of the rolls from Fig. 1. Fig. 4shows same parts as seen from the right of Fig. 2, and Fig. 5 shows.same parts as seen from the left of Fig. 2.

The same letters indicate the same parts in all. I

A A are the first set, or roughing-rolls; B B, the second set, orfinishing-rolls. O is the first platform, made in the usual way, andprovided with any suitable mechanism to raise it to receive the pile oringot from and to lower it to position to be fed into the rolls A A. Ois a similar platform on the other side of the rolls A A, which israised to feed and lowered to receive, in the usual manner. Above theplatform (J is hung the feed-roller D, in a frame, E, which is connectedto G by the rods 6 f and lever g, in such a manner that, when theplatform 0 is raised to receive the piece from the rolls A, thefeed-roller D is raised up out of the way; and when the platform 0 islowered to place, the feed-roller D is brought down to bear on thepiece, and, receiving motion from shaft h, the roller D feeds the piecepromptly into the rolls A A, the attendant having given the proper turnto the piece or billet while the platform 0 was descending. The platform(J is provided with a similarlydriven feed-roller, D which is soconnected to the platform (3 by its connecting mechanism that, when saidplatform 0 is down in position to receive the piece,'the feed-roller Dis raised out of the way; and when said platform is raised toposition'to deliver, the roller D is brought down on top of the piece,and feeds it into the rolls. This platform 0 is also provided with tworods or shafts, it, on which are four dogs,jjjj, and at their ends twoarms, is 70, which, when the platform is raised, hit

the inclines on the lower parts of standards L L, (see Fig. 5,) and turnthe shafts M partially, causing the dogs jjjj to rise and move the pieceon the rollers in platform 0 to the right place before the feed-rollerbears on it; the upper parts of the standards L L being straight, thedogs are moved only during the first part of the movementof platform 0and, as the platform descends, the said dogs turn back of their ownweight, faliin g below the surface of the rollers in platform 0 out ofthe way, the attendant having given the turn that the work may requirewhile the platform was ascending. When the billet comes from the lastpass of the rolls A A, the arms M M stand ready to receive it, as inFig. 4, and, being turned with their shaft N, (by any suitablemechanism,) carry or transfer the billet to the projecting rollers ofplatform 0 which is raised to receive it, so that its feedroller D shallbe up out of the way. The platform G and arms then descend together,and, as they arrive in place, the feed'roller D bears on, and deliversthe billet to the rolls B I B, it being turned the usual quarter-turn bythe arms M in the transfer. The platform is made narrow, so that theprojecting rollers may be in the right position for the first pass ofrolls B B and the stationary inclines 0 0. Figs. 3 and 4, are so placedbelow the frame of said platform 0 that, as it is lowered afterreceiving the piece from the rolls B B, the piece shall hit the slopingsides of the inclines 0 o, and be moved on said platform 0 sidewise tothe next pass. The platform 0 is provided with slides pp, carrying thedogs 0'1", Figs. 2, 3, and 5, so arranged as to be moved by the arm S,Fig. 2, in the slot t, Fig. 5, sidewise altogether during the first partof the rise ofthe platform 0 so as to move the piece on it to positionfor the next pass before the feed-roller D meets it, which it does oncoming to place, and feed it into the rolls B B. The platforms (3 and Gare pivoted at their outer ends, and are provided with a suitablemechanism to raise and lower them to the necessary positions foroperation with the feed-rollers 1) D which are connected to each of saidplatforms in the same way as the feedrollers D D are to the platforms 0O of the other set of rolls A A. At D Fig. 1, is shown an arrangementadapting our invention to boiler-plate mill work, the driven feed-rollersliding in boxes on the rods 4; o, and operated by lever W.

We claiml. The driven feed-rollers D D, operating on the top of thebillet, pile, or ingot, in combination with the supporting-rollers inthe platforms, when constructed and operating substantially as and forthe purposes set forth.

2. The swinging feed-rollers D D D D and the platforms 0 O G 0 soconnected by the levers g and rods 0 f, or similar mechan ism, that wheneach of the platforms receives the billet, pile, or ingot from the rollsthe feed-roller shall be raised up out of the way, and when moved toposition for entering the rolls the feed-roller is made to bear on topof the piece and feed it to therolls, substantially as described. I

3. The dogs jjjj and r r r r, operated by the moving platforms 0 ,0 andstandingpieces L L and t, in combination, as set forth.

4. The receiving and transferring arms M M, in combination with the twosets of rolls A A and B B, as and for the. purposes described.
